update firmware via uart from android

[Lurn_Z]

Hi all,

I use nRF52832 connect a android device with uart, and I want to update firmware via uart.

I can update my nrf device success on pc for test with the help of your colleagues and this link.

But I have no idea how to do this on android device.

And if I don't want to use nrfutil do you guys have any other example for me to update the version?

Any help or suggestion is appreciated!

Best regards

Hi

Can I use the nrfutil-linux in this link nrfutil releases on my andriod device.

If I can use it how do i use it?

And when I update on PC, use this cmd to update, it will stay here for almost 30 seconds before upgrading. Is this normal?

nrfutil dfu serial -pkg XXX.zip -p COM3 -fc 0 -b 115200

Best regards

Hi Lurn,

I am not sure if it is possible to run Python scripts on Android? If it is, then you could try run the script directly as explained here: https://github.com/NordicSemiconductor/pc-nrfutil/tree/v6.0.0#running-from-source. Another alternative is to implement your own DFU controller following the protocol specification from the SDK documentation here: DFU protocol

Maybe you are seeing the issue discussed here:  nrfutil takes 34 seconds before starting dfu  ?

Hi Lurn,

Windows, Linux or universal?

The script is common to all platforms. Installing it on a Linux system will make it compatible with that system.

Hi Vidar,

Vidar Berg said:

Thanks for confirming. The other common reason for the error is when the target device is not in DFU mode. Do you have a way to confirm if the device is in DFU mode? 

Sorry for this question.

When I program mbr and bootloader without application, it upgraded successfully, so maybe my cmd to enter DFU mode not worked, I will check it.

About the version number, can I get/set it in my code instead of nrfutil?

Best regards,

Hi Vidar,

I want to check application version when device is updated, how to do this in code?

Best regards

Hi Lurn,

No, because the version number is specified by the signed init command (see Init packet).

You can read the app version from the bootloader settings page @ 0x7F000 (nrf_dfu_settings_t ).

So, I can get the app version use this code in bootloader, but can not modify it in code?

    nrf_dfu_settings_t my_dfu_settings;
    memcpy(&my_dfu_settings, (uint32_t *)BOOTLOADER_SETTINGS_ADDRESS, sizeof(nrf_dfu_settings_t));
    uint32_t my_app_version = my_dfu_settings.app_version;

Best regards,

Hi Lurn,

Can you please explain what you are trying to achieve? I.e. why and when it is you want to change the version number  from the application?

[Lurn_Z]

Hi Vidar,

I want to check and change the version number when updating the device, just a question about modifying it in the code.

And the format of the version number can only be a number of type uint32_t, right?

Best regards,

Lurn

[Vidar Berg]

Hi Lurn,

You can read the version number from the application, but not change it.

The version number can be specified as an integer or a version string (converted to an integer). From nrfutil's help menu:

  --application-version INTEGER   The application version.
  --application-version-string TEXT
                                  The application version string, e.g.
                                  "2.7.31". Will be converted to an integer,
                                  e.g. 20731.

Best regards,

Hi Vidar,

Thanks for your help. I will try it.

Hi Vidar,

I used the DFU master code from here to test the process .

I can transfer files but never succeed.

The process is as follows.

1. I flash the DFU master application on the master board.

2. make sure my target board in DFU mode.

3. program the init.bin and app.bin to master board.

4. connect master board and target board.

5. run the DFU master.

In source code the application_image_address = 0x30000;

and I get error like this

In readme it shows the address.

so I change the application_image_address = 0x10000;

the error log is here
